TTArtisan 7.5 lens.

[kah loong Lee]

I am having trouble putting the image together with this lens in version 11. is there something to do with the updated version like the 12.8 lens data base? 

it always come out with no control point if I do it in version 11. but if I do it in version 12 trial every thing seems fine!. 

any help?

Hi,

The lens profile was added to PTGui 12 recently (and not to PTGui 11).

You should be able to get it to work in PTGui if you use:
Generic Fisheye lens
Focal length: 9.2 mm

The lens is not actually 7,5mm, somehow both of the TTArtisan fisheye
lenses are mislabeled.

Kind regards,

I had no problems stitching your images with V11.  I did the following:

1. Load in the images (first six - #7 is a duplicate)

2. Enter crop size 1 then click OK

3. Enter focal length 10.3 and select Generic Fisheye Lens in the Lens Type field

4. Click OK

5. Select the Crop tab from the list at the side, and drag the crop circle to position it just inside the blue edge of the image circle if necessary. (click&drag the edge to alter its size).

6. Reselect the Project Assistant tab and click Align Images.

If that doesn't work, select Advanced mode (at the left) and open the Lens Settings tab.  Compare settings with mine (I entered 9.2 as the estimated focal length):
